G'day kcott,

A few months ago, a mysterious anonymonk popped up out of nowhere to claim the fastest Perl solution in the long-running Long List is Long saga by utilizing Judy arrays ... then just as mysteriously disappeared again. Sadly, I doubt we will hear from him/her again. :-(

While I was watching agog from the sidelines, the remarkable marioroy got his hands dirty with the Judy C code, so I expect he'll reply to this thread on his return.

Some references:

• Re^2: Rosetta Code: Long List is Long by anonymonk (Dec 2022) - used Judy::HS in a Perl solution to Long List is Long (see also responses from marioroy)
• Re^2: Rosetta Code: Long List is Long - JudySL summary by marioroy (Jan 2023) - AFAICT, llil4judy is C/C++ only
• Judy Array References - my list of references on Judy arrays (if you know of other useful references, please let me know)
